Chapter 7B - Force & Newton's Laws

Question 0

What is the difference between balanced and unbalanced forces?

Answer 0

Balanced forces keep an object in place by canceling each other out. However, unbalanced forces cause an object to move because at least one of the forces isn’t canceled out.

Question 1

What is force?

Answer 1

A push or pull on an object

Question 2

Name 4 types of friction.

Answer 2

1. Static Friction
2. Sliding Friction
3. Rolling Friction
4. Air Resistance

Question 3

Newton’s First Law of Motion

Answer 3

“When all forces acting on an object are balanced, the object’s motion does not change.”

Question 4

Newton’s Second Law of Motion

Answer 4

“When at least one force acting on an object is unbalanced, the object accelerates in the direction if the net force.”

Question 5

Newton’s Third Law of Motion

Answer 5

“When one object exerts a force on a second object, the second object exerts and equal and opposite force back on the first object.”
